A-1519-II-NR Single-Axis Target

A-1519-II-NR Single-Axis Target


The A-1519-II-NR Single-Axis Target is a non-wireless variant of our A-1519-2.4ZB Wireless Target.  It has the radio taken out for applications in RF-senstive areas.  It has the same high resolution of .00002 in. (0.0005 mm) and accuracy with a large measuring range of ±.55 (±14 mm).  It can be used with all of HLI’s scanning lasers and data is displayed in either the R-1308 Single-Axis Readout or in our software  using our 151945 4-Port RS485 Communications Hub.  As with all our targets, the data for these targets updates in real time.


  • Caster Segments
  • Boring Mills and Large Lathes
  • Gantry, Spar Mills and VTLs
  • Horizontal & Vertical Machining Centers
  • Injection Molding Machines
  • Machine Bed Leveling
  • Presses
  • Roll Alignment


  • Operates in Single-Axis Mode with our continuously sweeping lasers (L-730/L-740 series) for measuring the flatness, straightness, squareness and parallelism of both machine tools and rolls.
  • Features 2-axis position-sensitive detectors with automatic background-light correction for extremely accurate readings.
  • Two options are available to display the target data:
    • R-1308 Single-Axis Readout
    • 151945 4-Port Communications Hub and using our Windows-based PC software.
  • Resolution of .00002 in. (0.0005 mm) and a measuring range of ± .55 in. (± 14 mm)
  • Linearized accuracy of ± .00015 in. (±0.0038 mm)
  • Targets can be used out to 100 feet (30.5 mm) from the laser.
  • The A-1519 package include the target, a magnetic base and three insert posts: 6.25 in., 4 in., and 2 in. (158.8 mm, 101.6 mm and 50.8 mm) for coarse height adjustment
  • Completely automatic on/off operation with no switches, wires or connections. The target activates when the laser beam sweeps across the target cell and flashing target LEDs provide immediate “on/off target” status
  • Powered by 2 internal lithium ion batteries for up to 11.5 hours of continuous use. Comes with AC adapter/charger, low battery and charging indicators.
  • Targets can also be charged with the optional A-1519CS-4 Charging Station that charges up to 4 targets simultaneously.
